BAcrfand FRANK G. MARBAGH, citizensof the United States, residing atLakewood,

in the county of Cuyahoga and State of Ohio, have invented certain'newand useful Improvements 111 a VVaslnng Mach ne, of

Thepresent invention relatesgto an improvement 1n. wash ng maclnnes, andthe general object of .theinvention. is to: provide a simple andeffective plunger attach ment fora tub orlaundry tray Wherewith toagitate the'waterand promote the 'wash is also particularlyconstructedto be conthis attachment is also constructed to pro duce anefficient I agitating and washing acveniently thrown back .and outof thetub" to givefree access to the washing compartment when the device isnot inoperation. A depressible plunger orrcup form ng part of tionwith-the application of a minimum of power, that is, the: plungerembodies a valve adapted togperinit the water to pass freely through thesame upona down stroke and v,thento be bodily lifted and cascaded overthe goods upon 'the reverse or up strokes.

"A cross pin 35 inarod' 33"serves to rotatetube 34 but is" 'freeto slidein a longitudinal slot 36 therein, and. acoiled compression spring 37d sleeved on rod 33 presses against thelower end of I the tube and. prov des a" yielding power-trans1nittingconnection for 0scilla tory lever 32 whereby when the oscillatorymovement of the lever is checked or meets with considerable resistanceat its plunger end the crank 31 may continue to revolve withoutstraining: or breaking the operating parts or injuring the goods withinthe tub.

The oscillatory beam or lever 32' is provided with pivot trunnions 38which are seated upon a pair of forked posts 39 extending upwardly froma cross bar 40 spanning the top of the tub or tray. Bar 40 is formedwith diverging arms 41-41 at its rear end which are hinged or rotatablyconnected to the upper ends of apair of clamp ing brackets 4242stationed at the rear of the tub and detachably secured to one of thewater-supply pipes,lower pipe 9 in this instance. The upper portionofeach bracket 42 is relatively thin and lies closely againstthe rearwall of thetub to permit upper pipe lOto extend past the brackets towardthe right end of the tub if a water supply connection is to be made fromthat end instead of from the opposite or left end as delineated in Fig.2.

The front end of oscillatory lever- 82 is bifurcated and slotted toloosely confine a pivot block or holder 48 through which the round stem44 of a washing o-r agitating plunger 45 is adapted to extend, and athumbscrew 46 secures stem 44 adjustably within holder 43. The lowerendcof plung or stem 44 extends through a packed boss or bearing 47 atabout the middle of bar 40 and the agitating plunger 45 is fixed to thelower end of this stem 44 and adapted to be reciprocated verticallywithin the tub when bar 40 spans the top thereof. Plunger 45 is of anelongated or rectangular shape and dished or open at its bottom, and hasslightly inclined or flaring side, walls 48 and a substantially flat top49.- The. top of the plunger is preferably slightly depressed betweenits borderedgesor else provided with a rounded border bead or rib 50 toform a shallow water collecting basin 51 at its top. The middle topportion ofthe plunger is also preferably provided with a series of waterescape openings 52 radially in respect to its stem 44, and a fiat rounddisk of rub ber or leather 53 sleeved upon or fixed to the stem isadapted to cover and close these openings and function as a flap valvewhen the plunger moves upwardly. downward stroke of the plunger part ofthe water beneath the plunger passes freely through openings 52 andcirculates beneath the disk or valve. The water in the tub is thus notmerely agitated but is also caused to circulate from the sidesof thetubto the center and upwardly through the plunger, when the plungerdescends. Upon its reverse movement upwardly the water caught orcollected on top of the plunger and valve is lifted and cascaded in alldirections from Upon a r the plunger toward the sides of the tub, andthe flat depressed top of the'plunger promotes this cascading efiect andcauses the water to throw outwardly a substantial distance-beyondtheberder edges ofthe plunger. A rectangular or elongated form ofplunger-also serves to distribute the water efiectively to all cornersof a square or rectangular compartment, and division walls 54 may beused to divide the plunger into separate middle. and end chambers orvpockets 55 and 56', respectively, the middleapocket alone having thewater escape openings 52 if desired, see Figs, 9 and 10.

Hinged bar 40 is preferably ribbed lon- -gitudii1ally at its top tostrengtlienlit and also to provide a seating channel lengthwise thereoffor a supplementary fastening bar 55 having a slanting clamping flangeor eX- tension 56 its outer end which'n'iay be shifted under math andagainst the overhanging sloping front wall 36 of the tub when bar 40 isplaced at rest upon the top vedges of the tub. A locking screw 58 passesthrough a slot in handle bar 55 and engages main bar 40 in securing thesaid parts in immovableposition upon the tub, butwhen these parts areunlocked the main bar, together with the plunger, may be raised andthrown back into an upright inclined position above therear wall of thetub substantially as shown in Fig. 6. However this cannotbereadilyaccomplished unless oscillatory lever 32 is permitted to free itselffrom the forked posts 39 upon bar 40. It is for that reason that thetrunnions 38 are seated in the open forked ends of said posts. Ontheother hand it is also desirable thatv when the bar and plunger aredown and the. plunger is operating that the trunnions be held securelywithin the. forked posts. Therefore a pair of hooks or catches 60 arepivotally mounted upon the outer sides of posts 39 to engage theprojecting ends of trnnnions 38 when the latter are seated within theforked ends of the posts, and in order that convenient; locking andunlocking of the hooks or catches may be effected the suppleinental'bar55 having handle 57 is divided at its inner end to straddle the boss orbearing part 47 at the top of main bar 40 and to extend a notchedextremity 61, beneath a depending linger (52 on each hook 60. Thus whenhandle 57 is pulled forward to unlock main bar 40 from the tub thecatches or hooks 60 are thereby rotated sufficiently and a loop-shapedhandle 57 at 1 the motor bfy of the belt-shifting 'de-' vice and thenpull out handle 57 and raise the hinged bar'to the inclined restposition shown in Fig. 6. (lo-acting stop lugs or shoulders 53' are alsoprovided on brackets 42 and the hinged arms ll to limit the rearwardlyswinging movement of barcarrying plunger 45, and a flat sheet-metalvplate,

6-1 secured to the bottom of bar 40 complete ly coverssthe washingcompartment when the bar and said cover plate is lowered and at restupon the-top of the tub. Agitation of the water andwashing of, the goodsthus takes place in a closed compartment, entrance to which ishoweverconveniently accessible at all times, and from which'eom partmentall operating parts may be quickly removed by merely lifting coverplateo through the medium of hinged bar 40 and 1 handle 57. Cover plate64: is preferably made with a hinged section 65' to permit con'ipartment4L to'be partlyuncovered for inspection of the goods or operationswithin the tub when the 'fmain. section or plate (34. is down uponthetray, and the position of downward movement of said. rod.

Spring 87 permits theplunger to yield under excessresistanceon its down stroke, and the'connecting'rodand tube and pivoted lever provide flexible power connections adapted to permit the cover and plunger to swing freelyabovethe tub. -What we claimis:
